Find someone to help me figure out how many meters the wood can have, 3 meters in length, 10 cm in diameter, 2 pieces, 12 cm, 11 pieces, 14 cm, 6 pieces, 16 cm, 4 pieces, 18 cm, 1 piece 4 meters long, 0.8 cm in diameter, 19 pieces, 10 cm 97 pieces, 12 cm 73 pieces, 14 cm 45 pieces, 16 cm 30 pieces, 18 cm 6 pieces, 20 cm 7 pieces, 22 cm 1. I won't do this with help There are still three meters above

4×8×19＝0.589
4×10×97＝4.365
4×12×73＝4.526
4×14×45＝3.735
4×16×30＝3.180

A 4.5-meter-long cuboid wood is cut into three sections, and its surface area is increased by 0.24 cubic meters. What is the original volume of this wood

The cross section is divided into three sections, and the surface area is increased by four cross sections,
So 1 cross-sectional area (bottom area) = 0.24 △ 4 = 0.06 square meters
So the original volume of wood = bottom area × length = 0.06 × 4.5 = 0.27 cubic meters

Saw a 24 meter long cuboid wood into six sections along the length, and increase the surface area by 240 square decimeters. What is the original volume of this wood?

10s = 240, s = 24 square decimeter = 0.24 square meter, v = 0.24 * 24 = 5.76 cubic meter
